M ECHANICAL MOTOR.

SPECIFICATION forming part of Letters Patent No. 565,200, dated August4, 1896. Application filed June 17, 1896. Serial No. 558,089. (Nomodel.)

To all whom it may concern.-

Be it known that I, FRANK P. BISHOP, of Marion, county of Marion, Stateof Ohio, have invented certain new and useful Improvements in MechanicalMotors, of which the following is a specification, reference being hadto the accompanying drawings.

The object of my invention is to produce an improved mechanical motorwhich can be constructed at comparatively small cost, can be operatedconveniently, and can be used for running all kinds of light machinery.It is shown as applied to the operation of a pump, but I do not confineits use thereto.

In the accompanying drawings, Figure I is a side elevation of my motor.Fig. II is a view taken at right angles thereto, partially in section.

1 indicates the frame of my machine, which is preferably made of metaland of oblong rectangular shape, designed to accommodate, in suitableboxes 2, a train of gears 3. One of the last gear-wheels 4 that iscomprised in the train of gear, preferably the uppermost one, has itsshaft 5 prolonged to accommodate on one end an eccentric wheel 6, towhich, as by a wrist-pin 7, a pitman S is secured. The other end of thepitinan drives a block 9 in ways 10, and is designed to impart motion,as to a pump 11. The opposite end of the shaft 5 carries a fly-wheel 12and an escapement ratchet-wheel 13. The movement of theescapement-ratchet is controlled by a tappet 14, which is actuated by apendulum-bar 15, pivoted to a stud 16, the pendulum-bar being provided,as usual, with a bob 17 The terminal gear-wheel 18, at the opposite endof the train 3 from the wheel at, is the main driving-gear of the train.Its shaft 19 carries a hollow cylindrical head 20, which revolves withina box 21, supported by a standard 22. Between the box 21 and the mainframe 1 of the machine the head is provided with an annular interiorchannel 23, to the exterior of which are secured, as by bolts 24,annular flanges 25. These flanges are designed to revolubly confine asheave-rim 26.

2'7 indicates brake-shoes carried between the exterior of the head andthe rim and which are designed by being forced against the interior ofthe rim to firmly secure it to the head. Then the shoes are thus forcedagainst the interior of the rim, the rim revolves with it and becomes apart of the head. \Vhen the action of the brake-shoes is relieved, therim revolves freely around the head within the flanges 25.

For operating the shoes I prefer to employ a screw-bolt 28, having anannular groove 29 in its head 30, which engages with and actuates theend of toggle-levers 31, that are respectively pivotally carried uponthe shoes, as between bearing-jaws 32 and 33.

3% indicates a ban d-wheel which screws on the screw-threaded end 35 ofthe bolt 28 and which, being confined by abutment-screws 36, working ina groove 37 in the periphery of an internal flange 38 thereon, isdesigned to force the bolt longitudinally in and out and thereby toactuate the shoes.

39 indicates a cog-boss on one side of the rim 26, and 40 a cog orratchet boss on the other side thereof.

41 indicates a gear carried in a frame 42 and meshing with the boss 39.

43 indicates a drive-pinion designed to be actuated by a hand-crank a4and to impart motion to the gear 41. The pinion a3 is movable in theusual manner to and from the gear ll, so as to be coupled with oruncoupled from it.

l5 indicates guide-pulleys, i6 aweight, and 47 a flexibleconnecting-piece, as, for instance, a rope secured at one end to theweight and passing over the pulleys and secured at one end to the rim26.

49 indicates a spring-actuated pawl carried in a case 50 in operativerelation to the cog boss 40, and adapted to prevent the unwinding of themachine or to secure the fixed portion when required. The pawl may beactu ated by adjustable lever 51, as illustrated.

In operation, the bolt 28 being driven inwardly, the brake-shoes releasethe rim which through the operation of the pawl sustains the weight to.The operator next throws the pinion 43 into mesh with the gear i1 and bymeans of the crank at winds the rope upon the rim 2G. The pinion is thenthrown out of gear. The bolt 28, through the handwheel 34, is caused toactuate the shoes, and the rim is thereby secured to the head 20. Thepawl is then disengaged from the boss 40, and through the power of theweight 46 motion is imparted to the machine, the same being timed andregulated by the Vibration of the pendulum in the usual manner ofescapement mechanism.

That I claim is- In a mechanical motor, the combination, with a framedrivingshaft, driven shaft and intermediate gearing, of a hollowcylindrical head secured to the driving-shaft and provided with anenlarged cylindrical chamber, a sheave-rim revolubly carried upon theexterior of the cylindrical chamber and provided upon its periphery witha cog-boss and a ratchet-boss, a ratchet engaging With the Vratchet-boss, a cog-Wheel meshing with the cog-boss, means for applyingpower to the cog-wheel for actuating the sheave independ-
